l This present application is divided Jrom a parent case entitled Tank car." tiled bv me .Yovembern 1014` Serial No. construction being lshown and described in .said former application on which Letters Patent No. 1.199.816 issued ()ct. Il, 1916.

The object ot' the present invention is to provide a tank adapted for use in tank cars. which tank is thoroughly insulated and is ot' such construction that it may bc readily assembled for use and it possesses an additional feature oi' advantage in that should it become necessary to repair the inner tank shell or the outer tank shell. the outer `shell ma)Y be removed from the inner shell with a minimum amount ot' labor. andthe insulation may bey removed .so as to'expose the inner .shell which may be repaired and the parte reassembled or the inner shell may be used as a tank of a tank car'without the outer shell. it' such' outer shell has been removed.

The invention comprises two complete tanks. one of which is larger than the other, the inner tank being removably mounted in position within the elements comprising the outer` tank.

.\nother object ot' the invention is to provide means for insulating the interior tank and for securingsuch insulation in position.

(lther features ot advantage are that the elementsl comprising the outer tank'maj: be reassembled to t'orm a tank intlelnndcntly of the inner tank. it' for an v reason that and the invention also comprises means for anchoring the inner tank in position upon a car undertrame b v means ot' devices common to the art associated with special attachments for holding the two tank shells in proper posi-` tion.

. Referring specifically to the parts, 1 indi- Cates the inner tank shell which .is prefer tion'jand `with convex heads 2 of the type commonly found in tank cars.

' -3 indicates the outer shell which lis pros vided'with concave heads 4. It will be noted that the tank shell 3 is of considerably greater' length than is thel tank shell 1 yso that the flanges 5 o the concave head 4 may be riveted to said outer shell. It is under- .stood that the flan es 6 of the inn'er head 2 are likewise rivete to the shell 1 of the inner tank. v

` Interposed between thenuter and inner. shellsare secured sheets or blocks and 11 of'insulation'which may be of any preferred type but as shown in Fig. 8 the sheets or blocks 1D and 11 are arranged so as to break jliintsf-e-that is, the )oints between the i tion, binding Vthe inner tank sneet's 10 are covered by the body portions of `the sheets 11.

To secure the Vinsulation 10-11 in posiwires 12 are wrapped about shell 1 in the first instance, and secured, at convenient intervals apart, on such wires 12 are clips 13 which clips are provided Vwith outstanding projections 14, which projections, as will be noted from Fig.

-`8, overlap contiguous sheets 10 of the insucourse of insulation lation, and likewise lapped about the inner 10 are bil'ldi-ng wires 12"L which have strung thereon similar clips with similar offset portions adapted to overlap L firmlyingposition upon the inner tank by .rivets 17 which dome 15.

the insulation sheets 11 thereby securing both inner and outer layers of i insulation shell.

The inner tank shell is provided with a dome 15 andadoine head 16 secured thereto head telescopes with the lie-router tank shell is provided with a dome 18, which dome 18 has outstanding flanges 19 secured to outstanding flanges 20 of its dome head 21 by vertical riv ts 22 and intermediate the domes 15 and 18 i sulation 2,5 is?" packed so as to thoroughly insulate lig,v such dome portions of the tank though it is the dome heads 16 annulanmember having to be noted that the insulation 25 is not of the block or sheet'lform.

The dome cap 26. is of' peculiar construction and'is lled with insulation This cap is provided with screw threads so. that it may be removably secured in position. Bv referring to Fig. 3. it will be seen that u and 21 are spaced apart, as are the shells 1 and il. To maintain these iiead` and the domes 15 and 18 in their spaar-1d relation, a .pan member 28 is einplplyed.

he pan 28 is preferably formed as an flanges at each end.

the threads formed on the cap ably provided with a cylindrical body por-` is secured to the dome head 21 by suitable means such as the rivets 30. The opening in the flange is threaded to coperate with 26. The other flange is inwardly turned, is riveted to inner dome head 16, andis also provided with an opening oraperture that registers with the aperture in the dome head 16. This flange is secured to the head by suitable means such as the rivets 29. Therap 26 is also provided with a Hangs' 33 that is of' a lesser diameter than the threaded portion, and' where the flange and threads meet, a shoulder is formed. Adapted to be removably secured on the flange 33, is a pan 31, the

-erably not riveted to the inner tank shell, but the inner tank shell preferably rests upon such supporting blocks and is secured in position by other means as follows:

t convenient distances from the longitudinal middle portion of the tank, angular members 42 are riveted to the bottom shell ot the inner tank through the legs 13 while the legs 14 depend vertically below the inner tank shell.

Riveted to the inner face of the outer tank shell. are angular members l5 whose horizontal legs 16 are riveted `to the outer tank shell ,and whose vertical legs 1T project upwardly'approximately in contact with' the depending legi-3.44- of the member 42 and as the members 42 are riveted to the inner tank shell and the members 15 are riveted to the outer tank shell,` it will be evident that inde- Y pendent longitudinal movement of the inner tank shell with relation 'to the outer tank shell is thereby prevented. Such longitudinal movement is likewise prevented b v the fact that there is interposed between the convex heads 2 and the concave heads 4 a filler of insulation which is intended to suhi stantially fill the gap between such heads 2 and Llthough it is preferred that the anchor ,members l2 and L15 shall be of suiicient strength to flue of the flanges is outwardly turned Vanlit/li"e horizontal leg 4:6 of the members 45 beand 47 before referred to anchoring the innerA tank in position with reference tothe v underframe.

As the underframe details fornrno part of the present invention and the tank forming the subject matter of this application is adapted to be used with various types of underfralnes,l I have indicated the under frame diagrammatically `in dot4 and dash lines `in Fig. l, which dot and dash lines indicate a car sill T0 which may be of any form, .and on the sill `7() I have indicated anchor stops Tl adapted to coperate with the tank anchor 6() to hold the tank in proper position and prevent excessiveA movement of the tank on the underframe.

To permit removal of thev outer shell ot the 'tank it is made separable as follows;

Attached tothe contiguous -edges at the upper side of the body of the tank are sections of what is commonly known as steel sheet piling ae-b one part a of a sheet belng secured to one tank sheet a and the other partV bof the sheet being secured to,

the contiguous sheet i A The sheet piling is commonly formed With edge portions adapted to interlock with other piling sheets of the same shape, but in the present use of. it the pilin sheets are cut so that one portion a maygbe'attached to the tank sheets andanotherportion of the same pilingsheet may be attached to other tank sheets and when brought together by longitudinal movement of the `tank sheets the piling will interlock and thereby connect such tank sheets together.

To connect other contiguous edge portions of the outer shell ot' the tank angles f', d, are riveted thereto as shown in Fig. 2, and bolts e or equivalent securing means are projected through the outstanding legs of such angles. It is evident that the outer tank shell is thus formed so as to be separable when desired. one manner of causing suchseparation being to remove the rivets or bolts connecting the concave heads to the sheets of such outer tank shell.

Olne of the objects of reu'loving the outer tank shell is to permit the 'inspection and repair of the insulation and the inner tank shell` and more frequently than otherwise it is not necessary to remove the entire outer shell. The usual inspection will require nothing more than the removal of bolts e', disconnecting the tank angles c and (l, and the rivets or bolts connecting sheets a with the concave heads l, whereupon the tank sheets a will be pivotally suspended from the interlocking sheet piling' sections. a and b. Tank sheets a may then be swung outu'ardlv and upwardly, such displacement of jects above dome head 21 of said tank sheets exposing tolview a large area of the insulation, which may be repaired or replaced if necessary.

Should there be any leakage in the upper partof theinner tank, the seepage of liquid therefrom swill find its way through the joints of the insulation toy the thereof, and cause aplainly discernible ferrousdiscoloration. The upper portion of the outer tank shell comprising the outer dome and outer. tank sheets a and b may be lifted as an integer, by a'crane 'or other hoisting means, after the rivets or bolts connecting outer tank sheets b andthe concave heads l have been removed. The repair of the upper part of the inner tank shell may then be made, or the contiguous insulation may Vbe inspected, replaced or mended.

1 'Ufteln theV bottom of the inner tank consists ot' a single metallic sheet as shown in' ,Fig l, and, in such case, there is little or no danger of repairs being needed in Vthis portion of said tank, occur, dome cap 26 mar be removed and a short beam be inserted into theinterior ot' the inner tank shell. -Such beam is then turned toa horizontal position tumore than vspace the dome opening in 'the 4inner tank shell, and the chains or cables of a crane or hoist are then passed throughthe dome and attached to or about said beam. A Winding up of the chains or vcables will then litt the inner tank shell and all the insulation covering the same away from the car underfralue and the bottom sheet ot' the outer tank shell.

The 4upper part of the outer tank shell havingI been removed, all of the insulation is exposed and the entire inner tank shell is readily accessible. y The insulated tank here illustrated is designed to hold volatile inflammable products having a vapor tension of over 10 lbs. per square inch at a temperature of 100 degrees Fahrenheit. Therefore, the dome cap 26 is not only screwed into pan 28', but is locked against withdrawal by means, best shown in F ig. 1, 3 and 10.

In said Figures, a vent pipe extends from the interior of the inner tank shell l through and above the dome head 21 of the outer tank shell, having a' cock or other valve attached to its upper end. A discharge pipe 76 is positioned on the opposite side of pan 28, preferably diametrically' opposite vent pipe 75, and also pro- I the outer shell and downwardly to the bottom of the. in-

tei'ior of' inner tank shell' I, Where it is held by a clamping device 77, seen best in Fig.. 1.

A closing cap 78V isscevvcd or otherwise secured to the upper en of discharge pipe 76 and has spaced outstanding lugs carrying a pivot pin.

Assuming a condition wherein the lading has established a relatively high vapor tension within inner tank shell'l. and desiring to `remove dome cap 26. it is first necessary vto turn cock handle 8l to vertical position.

when locking bar T9 maythe path of .withdrawal of dome cap 26. But such turning of cock handle 81 opens cock 80, allowing a rapid exhaust of the vapor creating the' tension in the inner v4tank By the time dome cap 26 has been unscrewed the vapor tension has been dissipated, removing the otherwise present danger of the `dome cap ,being blown into the face of the trainman or laborer removing it.

The'discharge of the fluid lading in inner tank shell 1 isaccomplished by making an air hose connection to cock 8O and opening the latter,'it being necessary to release lockhandle, unscrew discharge pipe cap 78. Pneumatic pressure being caused to pass through vent pipe 75 forces the iiuid lading to pass up through discharge pipe 76,

a hose is usually connected to the lading to any desired receptacle.
